Tradescantia sillamontana 'White Velvet', aka White Velvet, White Gossamer Plant, Woolly Wandering Jew, or Cobweb Spiderwort, is an evergreen perennial noted for its oval, stem-clasping, olive to gray-green leaves densely covered with silver-white, woolly hairs. The plant is so heavily covered with cobwebby, silver hairs that the plant appears almost silver.
